Function A is represented by the equation y = 4x - 2. Function B is represented by the table.

Which of these functions has the greater rate of change?

• Function A. It's rate of change is -2.

• Function A. It's rate of change is 4.

• Function B. It's rate of change is 2.

• Function B. It's rate of change is 6.

Answer explanation

Function A has a rate of change of 4, as indicated by the coefficient of x in the equation y = 4x - 2. This is greater than the rates of change for Function B, making Function A the correct choice.

Function A is represented by the equation.

Function B is represented by the graph.

Which function has the greater rate of change?

• Function A

• Function B

• Neither. They have the same rate of change.

• There is not enough information to answer this question.

Answer explanation

Function B has a greater rate of change as indicated by its graph, which shows a steeper slope compared to the linear representation of Function A. Therefore, Function B is the correct choice.

Constant rate of change is the same thing as...

• slope

• y-intercept

Answer explanation

Constant rate of change refers to the slope of a line in a linear equation. It indicates how much the y-value changes for a given change in the x-value, making 'slope' the correct answer.

• Equation, 17.5

• Equation, 7

• Table, 20

• Table, 5

Answer explanation

The y-intercept of the equation is 7, as seen in the function y=-\frac{2}{5}x+7. The table's values do not exceed this, making 'Equation, 7' the correct choice with the larger y-intercept.
